The great Korean Seon [Meditational Buddhism] Master Hyegeun Na-ong Hwasang Wangsa (1320-76) studied Seon under various masters in south China, and then under the great Indian Master Dhyanabhadra (the most important monk teaching in China throughout the 14th century) at Wutai-shan, where he met fellow student-monk Jacho Muhak-daesa (7 years younger). Upon his return to Goryeo he became abbot of Woljeong-sa here at Odae-san in 1360, and had a mystical experience of Munsu-bosal. In 1371 he became abbot of Yangju Hoeam-sa (Muhak lived together with him there), being simultaneously appointed Wangsa [Teacher of the King] and head of Jogye Seon Order. In 1376 he created the Munsu-hoe [Association dedicated to the Bodhisattva of Wisdom] together with Muhak, but died soon afterwards.
